2021–present Nissan KR engine - 1.5 L - KH5T, KR15DDT.2010–present Nissan HR engine - 1.0/1.2/1.4 L - HR10DDT, HR10DE, HR12DE, HR12DDR, HR14DDe (See Straight-4 below for other HR engines).The feature letters describe it as an engine with dual overhead camshafts, direct cylinder fuel injection with variable valve timing (bear in mind that the "V" designation is not used here, as that is used for variable valve lift) and is used as a power generator for electric motors. The HR14DDe engine is a good example of this, as this engine was purposely built for use with the EM57 electric motor as a power generator. ![]() Lastly, there are engines built specifically as power generators for electric motors, designated with the lowercase "e". Nissan does not have a letter designation for the SOHC configuration so the camshaft configuration type is assumed as SOHC if no letter is present.Īnother example is the MR16DDT engine, which has feature designations that describe an engine with dual overhead camshafts, direct cylinder fuel injection and a single turbocharger. The engine has a single overhead camshaft so there is no "D" listed in the name the camshaft type designation place being left out completely. The two features listed are electronic port fuel injection designated with the "E" and the presence of a turbocharger designed with the letter "T". The "V" designation is applied only if the engine has variable valve lift.Ī good example of an engine where not all of the feature designation spots are used is the L28ET engine. Many standard DOHC Nissan engines featured Variable Valve Timing, such as the VG30DETT, and as such do not use the "V" designation. For example, the SR20VE engine has dual overhead camshafts, but the variable valve lift design of the camshafts takes precedence in the naming scheme even though the "V" feature designation doesn't necessarily describe a DOHC arrangement. ![]() Not all features are necessarily described in the name. The (single) turbocharged version of the VQ displaces 30 deciliters (3.0 liters) and is logically called the VQ30DET. The feature letters describe an engine with dual overhead camshafts and electronic port fuel injection, but leaves off any power adder descriptors because it is a naturally aspirated engine. It belongs to the VQ engine family and displaces 35 deciliters (3.5 liters). The next example is the Nissan VQ35DE engine. It belongs to the VG engine family, displaces 30 deciliters (3.0 liters), and the feature letters describe an engine with dual overhead camshafts, electronic port fuel injection and two turbochargers. ġ = Camshaft 2 = Fuel delivery 3 = Power delivery 4 = Power adder 5 = 2nd power adder 6 = SpecialĪ good example to start with is the Nissan VG30DETT engine. The basic, common features follow this general order: The encoded letters that represent engine features follow a specific order and not all features are necessarily listed all of the time. Make note, the first few letters in the engine name that identify the engine family have nothing to do with these encoded letters for the engine features, and should not be confused as such.Įngines specifically built as a power generator for electric motors Below is a list of encoded letters, and the engine features they represent. Finally, the trailing letters encode the main engine features, and are ordered based on the type of feature. The following digits are the displacement in deciliters. The first few letters identify the engine family. Nissan uses a straightforward method of naming their automobile engines.
